1. DISTRIBUTION

The Hairy shield bug is one of the most common shieldbugs in the Netherlands with an exception for the northern provinces.  [1].
The bug occurs in herbrich biotopes, parks and gardens [1]. I hadn’t seen this stricking bug in the garden before, so a new garden species.

2. BEHAVIOUR

2.1. ACTIVITY

Adults can be found the whole year through and are most numerous in the period between April and November. They overwinter [1].

2.2. DEVELOPMENT

The larvae develop especially in plants from the rose family (Rosaceae) and are full grown in August [2].

3. IDENTIFICATION

The species is 10-12 mm in length. It is the only Shield bug with hairs on it neckshield.

These characteristics lead to identification [1, 2]:

  1. Pronotum (necksheild) and corium (frontal part of the frontwing) whinered
  2. Shield greenish to brown with a light tip
  3. Banded black and white connexivum protruding from below the wings
  4. Banden black and white antennae
  5. Hairy neckshield
